Among the following which metal is more reactive?

The correct answer is (c) Zinc
Explanation:
● Based on the Reactivity Series of metals, Zinc is more reactive than Iron, Copper, and Gold.
● Zinc can displace iron or copper from their salt solutions.
Information Booster:
● Potassium (K) is at the top of the reactivity series (most reactive).
● Gold (Au) and Platinum (Pt) are at the bottom (least reactive/noble metals).
● Galvanization is the process of coating iron with Zinc to prevent rusting because Zinc reacts with air first.

​Additional Knowledge:​

• (a) Copper: Less reactive than zinc; it does not easily react with acids.
• (b) Iron: More reactive than copper but less so than zinc. It rusts when exposed to oxygen and moisture.
• (d) Gold: Known for its low reactivity; it does not react with most acids, making it highly durable.
